Photoshop: How can I reset the Effects List order on left side of the Layer Style Dialog Box?

I've inadvertently typed a keyboard shortcut that has reset the Effects List on the left-hand side of the Layer Effects Dialog Box. I've tried resetting my PS Prefs (holding down Shift-Option-Command keys & getting the confirmation), and this hasn't helped. Can anyone please provide a solution? I need to take screen shots of the correct list order for a class I'm teaching. I'm really stumped...
And I really don't want to reinstall (heh-heh)

Thank you! I thought I was 'losing it.' I could swear I saw it 'jump/switch,' but it was 3:30 in the morning, so I was pretty fried. I checked the "Photoshop Reference" document, and, as usual, they were to busy or too lazy to update the screenshot diagrams. The programming team is quick to add new features/changes, but not too keen on documenting/updating them accurately.

I should have checked it out & compared it on/to one of my other Macs.
Again, thank you.
